[0042] Figure 4 FIG. is a schematic diagram of the working principle of a power supply distribution system for an automobile including a second power supply bus in an embodiment. Detailed Embodiment

[0043] In this embodiment, a power supply distribution system for an automobile is provided. The power supply distribution system for an automobile includes a first power supply bus and a switch control module. The power supply and use system for an automobile formed by connecting the power supply distribution system for an automobile and a plurality of in-vehicle electrical appliances to be powered and distributed is as Figure 1 shown.

[0044] Referring to Figure 1 , the first power supply bus may be in the form of a busbar, and the first power supply bus is connected to the first power supply module, where the first power supply module may specifically be a power source such as an in-vehicle generator, a power battery, or a storage battery. Referring to Figure 1 , the power supply and use system for an automobile includes a plurality of in-vehicle electrical appliances such as in-vehicle electrical appliance 1, in-vehicle electrical appliance 2, in-vehicle electrical appliance 3, in-vehicle electrical appliance 4, and in-vehicle electrical appliance 5. Among them, in-vehicle electrical appliance 1 may specifically be a wheel motor, in-vehicle electrical appliance 2 may specifically be an air conditioner, in-vehicle electrical appliance 3 may specifically be a headlight, in-vehicle electrical appliance 4 may specifically be an ambient light, and in-vehicle electrical appliance 5 may specifically be an audio and video entertainment system (including components such as a display screen and a speaker).

[0045] Figure 1 The switch control module in[] has functions such as data acquisition, data processing, and control switch connection. For example, the switch control module can collect data from the outside, process the collected data, and independently control the access switches of each in-vehicle electrical appliance to the first power supply bus according to the processing results.

[0046] For example, Figure 1 in, the switch control module may divide all in-vehicle electrical appliances such as in-vehicle electrical appliance 1, in-vehicle electrical appliance 2, in-vehicle electrical appliance 3, in-vehicle electrical appliance 4, and in-vehicle electrical appliance 5 into a first group of electrical appliances, so as to control all in-vehicle electrical appliances to be connected to the first power supply bus; Figure 2In this case, the switch control module can divide in-vehicle electrical appliances 1, 3, and 4 into a first group of electrical appliances, and divide other in-vehicle electrical appliances such as in-vehicle electrical appliance 2 and in-vehicle electrical appliance 5 into a second group of electrical appliances, so as to independently control in-vehicle electrical appliances 1, 3, and 4 to be connected to the first power supply bus, and independently control in-vehicle electrical appliances 2 and 5 not to be connected to the first power supply bus, that is, control in-vehicle electrical appliances 2 and 5 to be disconnected from the first power supply bus.

[0047] In this embodiment, for the in-vehicle electrical appliances controlled by the switch control module to be connected to the first power supply bus, such as Figure 1 all in-vehicle electrical appliances such as in-vehicle electrical appliance 1, in-vehicle electrical appliance 2, in-vehicle electrical appliance 3, in-vehicle electrical appliance 4, and in-vehicle electrical appliance 5, as well as Figure 2 in-vehicle electrical appliances 1, 3, and 4 in

[0048] the first power supply module outputs a power supply voltage and a power supply current to the first power supply bus, so that the in-vehicle electrical appliances connected to the first power supply bus obtain the power supply of the first power supply bus, and thus execute corresponding component functions. Figure 2

[0049] In this embodiment, for the in-vehicle electrical appliances controlled by the switch control module to be disconnected from the first power supply bus, such as

[0050] in-vehicle electrical appliances 2 and 5 in the switch control module can also control these in-vehicle electrical appliances to be isolated from the first power supply bus. For example, the switch control module can ground the power supply terminals of these in-vehicle electrical appliances, so that these in-vehicle electrical appliances do not obtain the power supply of the first power supply bus.

[0051] In this embodiment, by using a switch control module to divide each vehicle-mounted electrical appliance into a first electrical appliance group or a second electrical appliance group, and connecting the vehicle-mounted electrical appliances belonging to the first electrical appliance group to the first power supply bus and disconnecting the vehicle-mounted electrical appliances belonging to the second electrical appliance group from the first power supply bus, it is possible to distinguish different vehicle-mounted electrical appliances. For some of the vehicle-mounted electrical appliances, that is, the vehicle-mounted electrical appliances belonging to the first electrical appliance group, the first power supply bus is used for power supply, while for other vehicle-mounted electrical appliances, that is, the vehicle-mounted electrical appliances belonging to the second electrical appliance group, the first power supply bus is not used for power supply, so as to achieve precise allocation of vehicle-mounted electrical appliances, so that the power supply obtained by each vehicle-mounted electrical appliance matches parameters such as the life stage and fault status of the vehicle-mounted electrical appliance, which is beneficial to improving the fault troubleshooting of vehicle-mounted electrical appliances and the use experience of the vehicle.

[0052] For example, in the case where there is only one power supply bus, i.e., the first power supply bus, in the whole vehicle, the switch control module can detect each vehicle-mounted electrical appliance, divide the detected normal vehicle-mounted electrical appliances into the first electrical appliance group, and divide the detected abnormal vehicle-mounted electrical appliances into the second electrical appliance group. In this way, the detected normal vehicle-mounted electrical appliances are connected to the first power supply bus to obtain power for performing functions, and the detected abnormal vehicle-mounted electrical appliances are not connected to any power supply bus and will not obtain power, so as to achieve the suspension of use of the detected abnormal vehicle-mounted electrical appliances, enabling the vehicle user to timely discover, repair or replace the detected abnormal vehicle-mounted electrical appliances, which is beneficial to improving the use experience of the vehicle.

[0053] In this embodiment, referring to Figure 3 , the power supply distribution system for the vehicle is further provided with a second power supply bus and a second power supply module. The second power supply module and the first power supply module may be the same power supply module, such as the same generator, the same power battery or the same storage battery, etc. The second power supply module and the first power supply module may also be different power supply modules, such as the first power supply module is a generator and the second power supply module is a storage battery, etc. The first power supply bus and the second power supply bus are kept electrically isolated, so that the voltage fluctuations or current fluctuations of the first power supply bus and the second power supply bus do not affect each other.

[0054] In the case where the second power supply bus is set, the switch control module can connect the vehicle-mounted electrical appliances belonging to the second electrical appliance group to the second power supply bus, so that the vehicle-mounted electrical appliances belonging to the second electrical appliance group receive power supply from the second power supply bus. For example, referring to Figure 3 , in a certain time period, the vehicle-mounted electrical appliances 1, 3, and 4 belonging to the first electrical appliance group receive power supply from the first power supply bus, and the vehicle-mounted electrical appliances 2 and 5 belonging to the second electrical appliance group receive power supply from the second power supply bus; referring to Figure 4, in the next time period, the division of the first group of electrical appliances and the second group of electrical appliances changes. The in-vehicle electrical appliances 1, 2, and 5 belonging to the first group of electrical appliances are powered by the first power supply bus, and the in-vehicle electrical appliances 3 and 4 belonging to the second group of electrical appliances are powered by the second power supply bus.

[0055] For example, the switch control module can detect faults for each in-vehicle electrical appliance, and classify the in-vehicle electrical appliances without detected fault information (or detected fault information with a severity level lower than the threshold, such as "mild") into the first group of electrical appliances, and classify the in-vehicle electrical appliances with detected fault information (or detected fault information with a severity level higher than the threshold, such as "medium" or "severe") into the second group of electrical appliances. In this way, Figure 3 and Figure 4 in the system of, it is realized that the first power supply module and the first power supply bus supply power to the in-vehicle electrical appliances without faults or with minor faults, and the second power supply module and the second power supply bus supply power to the in-vehicle electrical appliances with faults or with major faults, achieving the precise allocation of the division and power supply of in-vehicle electrical appliances in different states, facilitating the vehicle users or maintenance personnel to troubleshoot faults (for example, only by detecting which power supply bus the in-vehicle electrical appliance is powered by, the fault can be found), and the first power supply bus and the second power supply bus are electrically isolated, which is beneficial to preventing the faults of the in-vehicle electrical appliances with faults or major faults from spreading to the in-vehicle electrical appliances without faults or with minor faults, thereby protecting the use safety and experience of the vehicle.

[0056] In this embodiment, the switch control module can also divide the first group of electrical appliances and the second group of electrical appliances according to parameters such as the expected remaining service life, and the same technical effects can also be achieved. For example, the switch control module can classify the in-vehicle electrical appliances with an expected remaining service life (absolute length or proportion of the total service life) greater than or equal to the threshold into the first group of electrical appliances, and classify the in-vehicle electrical appliances with an expected remaining service life less than the threshold into the second group of electrical appliances.

[0057] In this embodiment, the switch control module can also divide the first group of electrical appliances and the second group of electrical appliances according to parameters such as use risk information, and the same technical effects can also be achieved.

[0058] For any in-vehicle electrical appliance, its use risk information represents the magnitude of the risk of faults, fires, etc. when it continues to be used. Specifically, the use risk information can be determined by a single parameter. For example, the use risk of an in-vehicle electrical appliance usually increases as its expected remaining service life decreases. Therefore, the use risk information of an in-vehicle electrical appliance can be determined to be negatively correlated with the expected remaining service life of this in-vehicle electrical appliance.

[0059] In this embodiment, it is also possible to collect multi-dimensional operating condition information of a vehicle-mounted electrical appliance, and use methods such as an artificial intelligence model to process the multi-dimensional operating condition information, so as to identify the usage risk information of this vehicle-mounted electrical appliance.

[0060] For example, for the vehicle-mounted electrical appliance of the motor, parameters such as the percentage of the average rotational speed of the motor to the rated rotational speed, the percentage of the average operating temperature to the maximum tolerable temperature, the percentage of the average current to the rated current, and the percentage of the average vibration intensity to the maximum tolerable vibration intensity can be collected to form multi-dimensional operating condition information, and methods such as an artificial intelligence model are used to process the multi-dimensional operating condition information, so as to identify the basic risk information of this vehicle-mounted electrical appliance.

[0061] In this embodiment, the switch control module can also detect the driving task information of the vehicle, where the driving task information represents information such as the mileage that the vehicle has driven or is about to drive, weather, temperature, humidity, load weight, and number of passengers, and determine the risk coefficient based on this information. Generally speaking, the longer the driving mileage, the worse the weather, the higher the temperature, the greater the humidity, and the greater the load weight and number of passengers, the more adverse the impact on the usage risk of the vehicle-mounted electrical appliance. Therefore, the risk coefficient can be set as a positive number and is positively correlated with data such as driving mileage, temperature, humidity, load weight, and number of passengers.

[0062] After the switch control module obtains the basic risk information and the risk coefficient of a vehicle-mounted electrical appliance, it can multiply the basic risk information by the risk coefficient to obtain the usage risk information. By obtaining the basic risk information and the risk coefficient to determine the usage risk information, it is possible to comprehensively consider the usage risk of the vehicle-mounted electrical appliance itself and the promotion or inhibition effect of the driving environment of the vehicle on the risk, which is conducive to more accurately evaluating the usage risk of the vehicle-mounted electrical appliance.

[0063] In this embodiment, after the switch control module obtains the usage risk information of each vehicle-mounted electrical appliance, it can set a risk threshold, and classify those vehicle-mounted electrical appliances whose usage risk information is less than or equal to the risk threshold into the first electrical appliance group, and classify those vehicle-mounted electrical appliances whose usage risk information is greater than the risk threshold into the second electrical appliance group.

[0064] In this embodiment, by setting the second power supply bus, those vehicle-mounted electrical appliances in a bad state such as having a fault, a relatively serious fault degree, a relatively short expected remaining service life, or a relatively large usage risk can still obtain the power supply of the second power supply bus after being controlled by the switch control module to disconnect from the first power supply bus, so as to maintain the functional operation of the vehicle-mounted electrical appliances in the second electrical appliance group, enabling the vehicle user to have enough time for fault troubleshooting and other work to maintain the safety of vehicle use.

[0065] In this embodiment, the first power supply bus and the second power supply bus can use the provided power supply parameters (such as the same power supply voltage and maximum power supply current), or can provide the same power supply parameters (for example, the second power supply bus provides a lower power supply voltage and a smaller maximum power supply current). For example, when the switch control module classifies the in-vehicle electrical appliances with defective states into the second electrical appliance group, the second power supply module can be set to output power supply parameters such as a lower power supply voltage and a smaller maximum power supply current to the second power supply bus, which is beneficial to reducing the performance of the in-vehicle electrical appliances with defective states, reducing the possibility of deterioration of the defective states of the in-vehicle electrical appliances with defective states, prolonging the service life of the in-vehicle electrical appliances with defective states to maintain until the vehicle repair stage, and ensuring the use safety and experience of the vehicle.

[0066] In this embodiment, after obtaining the respective usage risk information of each in-vehicle electrical appliance, the switch control module can also perform the following steps to classify the first electrical appliance group or the second electrical appliance group:

[0067] A1. Set the first constraint condition;

[0068] A2. Under the constraint of the first constraint condition, classify each in-vehicle electrical appliance into the first electrical appliance group or the second electrical appliance group respectively.

[0069] In step A1, the first constraint condition is specifically that "the sum of the respective usage risk information of the in-vehicle electrical appliances classified into the first electrical appliance group is equal to the sum of the respective usage risk information of the in-vehicle electrical appliances classified into the second electrical appliance group". In this way, when performing step A2, the switch control module can first randomly classify each in-vehicle electrical appliance into the first electrical appliance group or the second electrical appliance group, and detect whether the respective usage risk information of the in-vehicle electrical appliances in the first electrical appliance group and the second electrical appliance group meets the first constraint condition. If it meets, the execution of step A2 is completed. Otherwise, the in-vehicle electrical appliances included in the first electrical appliance group and the second electrical appliance group are adjusted, and then it is detected whether the respective usage risk information of the in-vehicle electrical appliances in the first electrical appliance group and the second electrical appliance group meets the first constraint condition. If it meets, the execution of step A2 is completed. Otherwise, the in-vehicle electrical appliances included in the first electrical appliance group and the second electrical appliance group are adjusted... until the first constraint condition is met, or in the case where none of them meet the first constraint condition, among the multiple classification results of the first electrical appliance group and the second electrical appliance group obtained by performing step A2, select the classification result that is closest to the first constraint condition (for example, the absolute value of the difference between the sum of the respective usage risk information of the in-vehicle electrical appliances classified into the first electrical appliance group and the sum of the respective usage risk information of the in-vehicle electrical appliances classified into the second electrical appliance group is the smallest) for output.

[0070] In this embodiment, after obtaining the usage risk information of each vehicle-mounted electrical appliance, the switch control module may further perform the following steps to divide the first group of electrical appliances or the second group of electrical appliances:

[0071] B1. Set the second constraint condition;

[0072] B2. Under the constraint of the second constraint condition, divide each vehicle-mounted electrical appliance into the first group of electrical appliances or the second group of electrical appliances respectively.

[0073] In step B1, the second constraint condition is specifically "the sum of the first deviation and the second deviation is the smallest". Specifically, the first deviation is the deviation (i.e., the absolute value of the difference) between the sum of the usage risk information of each vehicle-mounted electrical appliance divided into the first group of electrical appliances and the sum of the usage risk information of each vehicle-mounted electrical appliance divided into the second group of electrical appliances. The second deviation is the deviation (i.e., the absolute value of the difference) between the sum of the power consumption of each vehicle-mounted electrical appliance divided into the first group of electrical appliances and the sum of the power consumption of each vehicle-mounted electrical appliance divided into the second group of electrical appliances. In this way, when performing step B2, the switch control module can perform multiple rounds of calculation processes (the total number of rounds is a fixed value). In any round of calculation process, the switch control module can randomly divide each vehicle-mounted electrical appliance into the first group of electrical appliances or the second group of electrical appliances and calculate the corresponding sum of the first deviation and the second deviation. After performing all rounds of calculation processes, select the round of calculation process with the smallest corresponding sum of the first deviation and the second deviation, obtain the division result of the first group of electrical appliances or the second group of electrical appliances therein for output, and complete the execution of step B2.

[0074] In this embodiment, the principle of performing steps A1 - A2 is as follows: By performing steps A1 - A2, the sum of the usage risk information of each vehicle-mounted electrical appliance divided into the first group of electrical appliances can be made equal to or approximately equal to the sum of the usage risk information of each vehicle-mounted electrical appliance divided into the second group of electrical appliances, so that the overall risk of the vehicle-mounted electrical appliances powered by the first power supply bus is close to the overall risk of the vehicle-mounted electrical appliances powered by the second power supply bus, reducing the concentrated outbreak of usage risks caused by the risk imbalance of the vehicle-mounted electrical appliances connected to the first power supply bus and the second power supply bus respectively (for example, a malfunction occurs due to the outbreak of the usage risk of a certain vehicle-mounted electrical appliance connected to the second power supply bus, resulting in a change in the power supply parameters of the second power supply bus and exacerbating the malfunction of other vehicle-mounted electrical appliances, and further leading to accidents such as load mutation of the second power supply bus). It can maintain the stable use of the first power supply bus and the second power supply bus in the case of insufficient performance of the second power supply module or the second power supply bus, which is beneficial to maintaining the safety of vehicle use.

[0075] In this embodiment, the principle of performing steps B1 - B2 is as follows: Steps B1 - B2 are equivalent to further introducing, on the basis of steps A1 - A2, the balance between the overall power consumption of each in - vehicle electrical appliance powered by the first power supply bus and the overall power consumption of each in - vehicle electrical appliance powered by the second power supply bus. This is conducive to balancing the overall usage risks and overall power consumption of the in - vehicle electrical appliances faced by the first power supply bus and the second power supply bus respectively, reducing the likelihood of a malfunction occurring due to the outbreak of the usage risk of the in - vehicle electrical appliances connected to a certain power supply bus, and maintaining the safety of vehicle use.

[0076] In this embodiment, the power supply distribution system for a vehicle and / or the power supply and utilization system for a vehicle can be installed on the vehicle, making the power supply distribution system for a vehicle and / or the power supply and utilization system for a vehicle a part of the vehicle, so that the vehicle as a whole has the technical effects of the power supply distribution system for a vehicle and / or the power supply and utilization system for a vehicle.
